Here is a sample XSLT 2.0 stylesheet that does the job with Saxon 9 and
the XML input samples you provided:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">

  <xsl:output indent="yes"/>

  <xsl:param name="url2" select="'test2009050404.xml'"/>
  <xsl:variable name="d2" select="document($url2)"/>

  <xsl:template match="/*">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <xsl:apply-templates select="*"/>
      <xsl:copy-of select="$d2/*/*[not(some $c in current()/* satisfies
(node-name(.) eq node-name($c)))]"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="/*/*">
    <xsl:copy>
      <xsl:copy-of select="*[not(some $c in $d2/*/*[node-name(.) eq
node-name(current())]/* satisfies (node-name(.) eq node-name($c)))]"/>
      <xsl:copy-of select="$d2/*/*[node-name(.) eq
node-name(current())]/*"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>
